it would be nice if you inform all of us in what kind of sub is it for, how many, what are your special request etc.. giving us details before we send you a PM will give us a good idea for your box.
They are two Infinty Reference 1242w 12's They need 1.25 cubic feet per sub, and I also would like a port on that. If you can see what you can do with that it would be nice.
Also does it matter if you have more airspace than it says. Because it says that you need 1.25 cubic feet what if I had 2.75 would that matter per sub?
